Multi-cluster IBM Fusion using Hosted Control Plane
Create Hosted Control Plane with OpenShift® Virtualization clusters on IBM Fusion with IBM Fusion services.
A single IBM Fusion hub deployment on Bare Metal can now support IBM Fusion services on OpenShift Hosted Control Plane clusters. Hosted Control Plane enables the nodes in the Bare Metal OpenShift Container Platform to host multiple clusters virtualized using OpenShift Virtualization. You can create clusters that match your specific workload needs, and clusters can be created on demand.
With Hosted Control Plane for OpenShift Container Platform, you create control planes as pods on a hosting cluster without the need for dedicated virtual or physical machines for each control plane.
For Hosted Control Plane, clusters can be created using IBM Fusion hub with storage as Fusion Data Foundation. The Fusion Data Foundation service needs to be deployed on the host (base) cluster in order to deploy hosted control plane clusters.
The IBM Fusion is referred to as the hub cluster and the IBM Fusion spoke is referred to as the hosted cluster.
To create hosted clusters, see Hosted control plane. To deploy storage client in the Hosted Control Plane clusters, see Installing Fusion Data Foundation on a Hosted Control Plane cluster.
- IBM Fusion supports Bare Metal Hosted Control Plane and virtual machine based multi-cluster using KubeVirt.
- The backup and restore of Hosted Control Plane clusters is not supported in IBM Fusion. If you want to do backup and restore of the cluster, see https://docs.openshift.com/container-platform/4.16/hosted_control_planes/hcp-getting-started.html.
- Support for deployment of IBM Cloud Paks and IBM Maximo® on Hosted Control Plane: IBM Cloud Paks support for IBM Fusion and IBM Maximo® Applications support for IBM Fusion.
- Bare Metal and virtualized Hosted Control Plane clusters are supported in connected environments including proxy.
- Bare Metal and Hosted Control Plane are supported in the offline environment.
